I found that more pts can be created this way.
- To reboot into text mode-tty1
startxto jump into gui mode.
To enter terminal in the gui mode started from tty1 to inupt.
this gui is pts/0
to input ctrl+alt+f2 to jump into
another text mode-tty2
startxto jump into gui mode, this gui is pts/1.
To enter terminal in the gui mode started from tty2 to inupt
Now two gui modes can be created.
How to know how many tty and pts are running at the same time on my pc?
Every gui program--include virtual terminal in gui is the client(or say slave) of x-server(or say x window system) ,so it was called pesudo terminal slave.
In my opinion,the proper sentence would be that:
but that's an application program in X server started from the tty1, but also a pts.
Please see the discuss here on :
From the knowledge,i draw my conclusion.
It not only an X server started from the tty1, but also a pts.
